Your body is a complicated machine. It uses food as fuel — the biological mechanisms behind this process are fascinating. Your hypothalamus, brain stem and vagus nerve work together with hormones in your gut to tell you what to eat and when to eat it.
Even though you’re a machine that functions as it should, you have on and off switches, too. Behavior and culture can many times override the biological function of eating and tell you when and what to eat. You might be full from dinner, but a late movie means you eat popcorn with a soda. You know that kale is good for you, but your culture tells you a green smoothie is the opposite of delicious.
It’s complicated, right?
Did you know that your food habits are what they are as a result of many different factors? They include:
You might think these factors don’t influence you, but humans are more influenced by social and environmental factors than we like to believe. In one study, one third of people said their food intake was based on the food intake of others.
Understanding what drives your decision to eat or not eat might help you get over a few hurdles as you’re on your way to building new food habits. Do you associate eating at work with feeling shame? Identify why you feel shame eating around others so you can integrate healthy foods into your work day. Do you overeat on Sundays because that’s your family tradition? Identify how you might make different choices at family dinner next week.
If you’ve recognized what influences your food choices and still struggle to make a change, there are a few science-based strategies that might help you get on track.
Nutrition is one domain in which good choices add up quickly. Take a minute to make a list of what you’ve eaten in the past 24 hours. Then, write down why you chose to eat what you ate. You might identify some interesting patterns that can help you make better food choices and build good habits.
